摘要
对某桥梁防撞结构的碰撞过程进行了数值模拟。介绍了船桥碰撞数值仿真中所涉及的关键技术,研究了船桥碰撞力,碰撞损伤变形、能量吸收及防撞结构各构件的变形情况,并对其进行了详细分析。数值模拟是用大型非线性动态响应分析程序MSC/Dytran来完成的。
The simulation of the behavior of the protection structure in collision is described. The key technique of simulation in ship-bridge collision is introduced. The collision force, the structural damage,the energy absorption capacity as well as the deformation of structural components of the protection structure are investigated in detail. The simulation was carried out by MSC/Dytran, a three-dimensional analysis code for analyzing the dynamic, nonlinear behavior of the structure.
